EAST LANSING, Mich. — Thousands of Michigan State students and fans celebrated the football team’s Big Ten title win Saturday night with large, rowdy bonfires.

East Lansing police arrested “multiple people” Saturday night near River and Cedar streets, Capt. Jeff Murphy said in a statement. No injuries were reported in what he called “a large civil disturbance.”

The No. 10 Spartans defeated No. 2 Ohio State 34-24 late Saturday, earning its first Rose Bowl appearance in a quarter-century.

Michigan State University President Lou Anna Simon issued a statement Sunday expressing pride at the victory and anger at the disorder, vowing punishment for any students involved.

“It’s more tradition than anything,” Joe Sheena, an MSU senior, told the Lansing State Journal. “We’re not a school of pyromaniacs.”

Murphy declined to release arrest figures Sunday, saying his department would have more details Monday morning. East Lansing police got help from Michigan State University police, state police and the Ingham County sheriff’s department, Murphy said.
